What are the negative & positive charged bodies on the basis of electrons?

Physics help! Electricity and Thermodynamics... FILL IN THE BLANKS?

• Use the following words to fill in the blanks: electric, 1.6 x 10^-19 C, removing, neutral, negative, positive, conserved Electrical interactions play a key role in the chemical bonding of matter and in most biological processes such as seeing, feeling, moving and thinking. Electrical interactions occur between bodies and particles which have ____A____ charge which, like mass, is a fundamental property of matter. Charge comes in discrete amounts and, like energy, it is always ____b_____. The SI unit of charge is the coulomb (symbol C). The smallest possible discrete amount of charge, the elementary charge e, has a magnitude of ___c______. There are two types of electric charge, which have been arbitrarily labelled ___d____ and negative. Every electron has a _____e_____ charge, of –1e ( -1.6 x 10^-19 C), and every proton has a charge of +1e. An atom or molecule which has acquired a net electric charge by the addition or removal of a whole number of electrons always has a charge which is some positive or negative integer multiple of e. The total amounts of negative and positive charge in the universe seem to be exactly balanced. Most objects normally have the same amount of positive charge as they do negative charge, and so are overall electrically ____f_____. However it is possible to “charge up” an object by adding or ___g______ some charged particles such as electrons or ions. When you make an object negative by adding extra electrons, you must be getting those electrons from something which is becoming positive. The total amount of charge is conserved; it is just moved around

• Answer:

  a → electric b → conserved c → 1.6 x 10^-19 C d → positive e → negative f → neutral g → removing
